In a move that is sure to get liberal snowflakes rushing to their safe spaces faster than ever, Princeton University is now encouraging students
to report “problematic experiences based on [their] identity.” This
means that if students find themselves in a situation that makes them
feel offended or uncomfortable in anyway, they can – and should,
according to Princeton – go tell somebody about it, even if it is
something that normally wouldn’t result in disci

It’s said that about 80 percent of New Year’s resolutions are abandoned by the second week of February.1
This means if you made one for 2018, there’s a good chance it may
already have failed. There’s also a sizable number of people who set no
goals at all, New Year’s resolutions or otherwise, in part because they
may not realize the importance of goal setting and in part because they
may not know how to do it.2
There are other reasons why you may avoid goal setting as well,

Beginning shortly after President Donald J. Trump defeated Hillary
Clinton in the 2016 election, Americans were treated to a steady diet of
stories from the American Pravda media claiming that he “colluded” with
the Russian government to “steal the election.”
For months information meant to substantiate the claim, made in the
absence of any real evidence, was “leaked” to various news outlets known
to be friendly to Clinton, Democrats, and every known enemy

It seems like every day you see, hear, or read about something that’s
being created or invented concerning all sorts of popular science
fiction technology, but a fully-working tractor beam was never among
them — until now. According to a team of engineers from the University of Bristol, they have successfully managed to develop the world’s most powerful tractor beam, and it’s capable of moving objects around using nothing but the power of sound.

That’s right, with the power of their newly-invented acoustic tractor beam,
the team of engineers was able to show that it’s possible to hold
particles in mid-air. So far, they have only tested it on a
two-centimeter piece of polystyrene sphere, but it’s a good start,
considering the technology could have lots of different applications —
out on land or even in other locations.

According to the researchers, they have been working on the
development of their acoustic tractor beam technology for a few decades
now. And a major obstacle has stood in their way: rotating sound fields
typically transfer some of their spinning motion to the objects that
they are supposed to hold, making them orbit faster and faster up to the
point that they become unstable.

Now, the team has managed to find an alternative to conventional
methods. The new way, in which the researchers created a device that can
create “mini tornadoes” from sound waves alone, is said to use a
spinning field to keep objects steady instead. The researchers are now
hoping to scale up the use of their technology in order to manipulate
much larger objects that they initial tests would allow them to.

According to Dr. Asier Marzo, the lead author of the study from the Department of Mechanical Engineering at the University of Bristol,
their breakthrough could provide the much-needed push for a
fully-developed and fully-working version that can truly be used for
some real-world applications. “Acoustic researchers had been frustrated
by the size limit for years, so it’s satisfying to find a way to
overcome it,” he explained. “I think it opens the door to many new
applications.”

According to a report, the breakthrough of the researchers comes from
the discovery that the rate of rotation can be finely controlled, and
that is by rapidly changing the direction of the vortices, which ends up
stabilizing the tractor beam. This then led to an increase in the size
of the so-called “silent core” that is actually where floating objects
lie on the tractor beam itself. And as its size increased, so too did
its capacity to hold solid objects.

In the end, the researchers settled on using ultrasonic waves that
were set at a pitch of 40 kHz, which is the same pitch as sounds that
only bats can hear, and then they used it to hold the two-centimeter
polystyrene sphere mentioned at the beginning of this article. The
researchers note that the sphere measures two acoustic wavelengths in
size and is so far the largest object yet trapped in a working tractor
beam.

Dr. Bruce Drinkwaterm, a professor of Ultrasonics from the Department of Mechanical Engineering at the University of Bristol, said that there is potential to use the new kind of tractor beam for other things in the future.
“Acoustic tractor beams have huge potential in many applications,” he
explained. “I’m just particularly excited by the idea of contactless
production lines where delicate objects are assembled without touching
them.

The world may be some ways from that, but it’s certainly not outside the realm of possibility.
